The real problem, IMNSHO, is that C doesn't allow a pointer to a pointer to a non-const object to be implicitly treated as a pointer to a pointer to a const object. C should have required those two pointer classes to have the same representation (which they would in any sane, and pretty much any insane, system) and therefore a lot of functions could have the additional consts added to their prototypes.

At least one can do casts on sane architectures... :-/
